What is a normal respiratory rate for a newborn? How does she handle a resp rate that is too high? Too low? Has she personally had any demises (mother or baby)? How many emergency transfers has she had? What kind of medical training has she had? How many births has she attended? Does she know the signs of placental abruption during labor? Does she know what the range of normal fetal heart tones are, and at what point will she transfer if they are too low?

Basically, you need to quiz her about everything that could go wrong, and see how she answers it. You also need to do your homework as well, so if she tells you that a newborns heart rate is 60 and its really 40, but you don't know that, then asking the question is useless, KWIM?
